To all whom it may concern:

Be it `known that I, ALFREDv S. MoCasirnY, a resident of Chicago, Illinois, have invent. ed a new and useful Improvement in Printing-Telegraphs', which invention is fully set forth in 4the following specitication. This invent-ion has general reference to electrical signaling or Vcommunication and relates more particularly to printing telegraph systems, though it will be understood from the drawings and the description thereof, that the principal features of the invention and much of the apparatus hereinafter described, are applicable to many different' industrial uses7 and may be employed Wherever it is desired to produce by electrical impulses distinct mechanical effects. In the following description, therefore, the designation of distinct functions .to certain parts of the apparatus and specific names applied to parts of the apparatus are not to be considered as limitations, but are merely used for convenience in describing the apparatus shown and its operation With .respect to printing telegraph systems.

Referring in general terms to the organized apparatus herein illustrated as embodying the several features of my invention, said apparatus embraces a transmitter pro vided, preferably, with a key board like a typewriter and Which, upon the actuation of a particular key, transmits a series of electrical impulses representing the character appropriated to that key. Said impulses are collected by suitable devices located at the transmitting station and sent out to line.

The manipulation of each key transmit-s a certain number of impulses, some of which are of one polarity and some of the other polarity, and each character to which one of the keys of the transmitter is appropriated, is distinguished `from all other characters by a particular permutation of the impulses. These impulses, Which'are collected and sent to line, act upon the receiving mechanism at the receiving station.

The electrical currents by which the impulsesl are transmitted may be all of one polarity, but it is preferred to use reversalsof current in connection With multiple sets of pole changers, five or more in each set', which areconnected with a main battery circuitat the transmitting station, andso l0- cated ,with respect to part-s operated by the keys thatthe normal position of one or more of the pole changers of each set is changed ed with the insulated segments ef a collect ing device, by which the impulses are collected and sentout to line. Eight sets of pole changers are herein illustrated. All of said sets of pole changers are placed in they@ path of rotation of an arm which is moved successively into relation. therewith by parts operated by key levers, whereby, upon depression of oneof the key levers, one or more of the pole changers of one set is shifted to its negative terminal, so that when the main circuit is closed through this particular set, one or more of the impulses sent out to line will be negative while the others will be positive. Associated with the severa-l sets of g@ pole changers is a single granted terminal which is connected with the main line and associated with said ground terminal is' a vibratory lever which is connected with the lcollector above mentioned and through g5 which, when said lever is in Contact With the ground terminai, the collected-impulses are sent out to line.

The collector consists cfa circular disk provided with a number of sets of insulated segments equal.' to the number of sets of pole changers, each set of segments having a number of segments equal to the number of pele changers in each set, and the pole y changers ci' each set being connected with 95 the segment of the corresponding set. A rotary arm carried by a central rotary shaft of the collector moves successively over said segments, said arm being rotated by an escapemeut' mechanism operated by a local 100 relayT circuit' of the main line. Said arm is provided with a tail'piece which mcves suc-l cessively over-an inner ring divided into a. number of insulated segments corresponding to the number of .the sets of pole changers.

rEhe segments of said inner ring are con-l nected with the oscillatory levers associated with the ground. terminal and when either of said levers is in contact with the: ground terminal, a circuit from the main battery is 11o closed to ont ietof the pole' changers, the segments cu the disk connected therewlth,

P01@l se The pole; changers. of each set are electrically connect- 55 rest over each set ofvpole changers and a2 key depressed, a permutation is made there -by to' correspond with the permutation of impulses to be sent to line. After such perl mutation is made the ground termina-l is closed to line. It is of no-consequence that the permutation set up by these pole chang:

ers be sent out to line at once in the form of impulses of different, polarity, as said pole changers will remain in' their relative positions until the lrotative arm thereover has completed -one revolution. Therefore, the impulses from each set lof pole changers may be sent outv to line during any time covering oneperiod of complete'rotation of said arm. Means are provided for restoring the pole changers before the arm is again brought to .rest thereon. The rotary arm of the collector will be adjusted to have a uniform speed of rotation and practically as great as the'average speed of the operator, including the necessary pauses in the work of the operator and it matters not if the operator manipulates the keys in advance of the operation of the line so long as the permutation set up in each set of pole changers are sent out in the form -of impulses before the rotary arm again reaches thatl particular set of pole changers. The operation of the line, therefore, is uniform `and the line need not be idle at any-\time although the operation of the keys maybe intermittent.

I am, therefore, enabled to provide a uniform and practical length of time for sending the impulses `.out to line, and for the Yoperation of the receiving apparatus. Any suitable receiving mechanism may be used with said transmitting device, the same preferably embracing a distribu ter, a selector and a printing device, the distributer distributing the impulses to the selector wherein they are translated into a definite mechanical effect and which mechanical effect may operate a typewriter, type wheels or other device. Preferably the receiving mechanism which is employed is that described and. claimed in my application Serial Number 534,482, filed December 22d, 1909, the same being a division of my application Serial Number 58,646, filed May s, 1901.

I will refer now in detail to the construction of the transmitting apparatus located at the transmitting station in connection..

C C designate a plurality of other levers,l

below the levers B pivoted upon a transverse rod A3 mounted inthe frame pieces A in advance of the rod A1. The rear ends of said levers C carry a plurality of raised bars C1. Each lever B is provided with one or less than five depending pins or studs b1 adapted to engage said cross bars C]L so that when a key B is depressed, one or more of the keys C will be also depressed. The levers C are divided into two sets, each set containing five levers. The forward ends of said levers C are connect-edwith live concentric rings D located in the same plane, one set of said levers being connected with the rings at one side of the center thereof,l and the other at the other side of said center. Supported on said base A, below the rings D, are a plurality of radially 'arranged plates E which carry on their upper margins a plurality of sets of insulated terminals e el, there being five pairs of such terminals in each set. One ofsaid terminals of each set is positive and the other negative. Pivoted to said plates E to vibrate in vertical planes and insulated from the plate, are a plurality of pole changers ez'which have their upper ends located between the terminals e e1. Said pole changers e2 normally rest in contact with the positive terminals e and are adapted to be swung into contact with the negative terminals e1 by means of plungers F carried by a radial rotary arm F1, which latter is connected with and rotates about acentral postor standard F2 mounted on the base plate A. The pins F are spring pressed and are each under one of the rings D and over one of the pole changers when the arm is broughtvto a rest, so that when one or more ofthe ringsare depressed by the depression of onel of the key levers, in the manner above neeaees indicated, one or more of said pins will be depressed and will engage one or more of the pole changers e2 to throw the same into contact with the negative terminals. For tlris purpose the-meeting ends of the pins andlevers` are taperedy as clearly shown in Flg-;2. i i

As herein shown, eight sets of pole chang- .ers are provided. All of the positive terminals of the pole changers are lconnected by wire l with one pole of a divided battery 2, and all the negative terminals are connected with the other pole of said batteryby a wire 3.' The pole changers e2 of each .set are connected by wires 4 with a like number of insulated' segments g of a collector disk G, there beingv as many'sets of segments as sets of pole changers and the number of segments in each set'being equal to the number of pole changers in each set.

F4t is a ground terminal which is mounted on the post F2 and insulated therefrom,and e"` is a switch lever, one for each set of pole changers, adapted to be swung into contact with the ground terminal. Said ground terminal is connected with the line wire 5.

G2 is a rotary arm mounted on the collector-shaft g1 concentricwith the annular series of the segments g. The outer end of the lever passes successively over said segments. Said arm is provided with a tail piece which moves in contact with a ring G1 concentric with the shaft g1 and consisting of a number of insulated segments equal to the number of sets of pole changers.- Each ofthe segments .of the ring G1 is connected by a Wire 6 with oneof the switch levers es; When the lever e3 contacts with the ground terminal 'F4 the circuit is closed through the battery 2, one set of theV pole chargers,'the segments g, the lever arm G2, one segment of the ring G1, wire 6 and ground terminal F4L and out to line 5. The line wire passes through the coils of a relay H, which operates a local circuit, including a magnet H1 and battery H2, the magnet operating an escapement lever H3 which -actuates an escapement mechanism forturning the arm G2 step by step, said escapement mechanism being substantially like the escapement mechanism for the distributer hereinafterto be described.

The arm F1 is adapted to be rotated step by step as the keys are depressed, and'its position 'of rest is always over one set of the pole changers. Said arm is given a step by step movement by the following mechanism: f designates a ratchet wheel which 'is rigid with a shaft on which the arm 1s mounted. Said wheel is adapted for enagement by a pawl f2 carried upon the iwer end of a vibrating lever F. The upper end of said leveris connected-with a jointed lever A4 low the base, the other pending from all of said levers, wherebyV upon depression of either of the key levers B, the pawl and ratchet mechanism is operated to move the arm F1 one step, or from one set of pole changers to the other.

The arm F1 is provided on its under side in advance, of the plungers F with a plurality of cam projections f3 whose oliice it is to restore the pole changers to the positive terminals just before the arm stops thereover. Said arm is also provided with another cam projection f4 located inthe rear of plungers F and adapted, after certain of the plungers F have moved certain of the vvpole changersinto contact with their nega-` tive terminals, to swing the switch lever e? against the ground terminal and close -the circuit to the line through said terminal.` In order toopen the line circuit to each of the sets of pole changers the plungers are brought to rest thereover in the next rotation' of the arm, the lever F is provided with a forwardly projecting cam arm f5 which swings the lever e3 of each set outV of contact with the ground terminal just before the'arm F1 is brought to rest over said set in the manner indicated in Fig. 8. It will be seen, therefore, that after one or more kpole changers of each set has been shifted in the manner described into contact with their negative terminals, thev circuit is closed to the corresponding segments on the disk G and remains closed during almost the entire subsequent rotation of the arm F1, in which time the arm G2 of the collector passes over the corresponding segments and sends the permuted impulses to the line.
